Since you have changed the criteria to „relatable“, I will definitely not say Awake – it’s way too disconnected for me to see it as a „real album“ as you do – for example I have absolutely no idea what Lifting or Scarred or The Silent Man are about (yes, I know what they’re supposed to be about, I just don’t hear it – or not enough to relate).
So, the most „real/relatable“ to me are (in order from most to least favourite):
SDOIT
Octavarium, which is very personal-problems-oriented (including the title track which I more or less interpret as a lament of an always-unhappy musician/artist, lamenting that he’s restricted by the laws of music itself, so his best works might always sound like another song/piece of art… Hence the „could this be everything“, the quote part and „trapped inside this octavarium“). Yeah, I know.
TOT
BC&SL, yes, including The Count (since I have experienced visits that made me feel really uneasy, like „am I safe with this guy?“) and the slightly-not-fitting-but-still-plausible Rite.
Most relatable for me is probably 8 or TOT, though.
